What does http-win.cpp:159 error mean?

Before you go looking for a solution to an error, it’s always recommended to have an idea of what’s wrong.

Jay Freeman aka Saurik has designed Cydia Impactor in such a manner that makes identifying errors a breeze.

http-win.cpp:159 error

The http-win.cpp:159 error goes something like this –

Peer certificate cannot be authenticated with given CA certificates SSL certificate problem: unable to get local issuer certificate.

You can also get another error message –

Couldn’t connect to server
Failed to connect to port 443: Timed out

It’s clear that the message signifies a problem with the signing certificate. Here are a few fixes that will certainly help you fix this issue once and for all on your iPhone, iPad, and iPod touch.

2. Switch your Internet connection

A faulty connection can also cause issues with Cydia Impactor. Even if your connection is working just fine, you can still get errors.

Try using another internet connection and check if the issue persists.

3. Restart your computer

While this is not a proper fix, some users are able to fix this issue just by restarting their computer.

4. Use a Mac

Surprisingly, the http-win.cpp:159 error only affects Windows users. So if you own a Mac, you are in luck.

To fix it, simply run Cydia Impactor on a Mac or a Mac VM on your Windows setup. If you have a Linux machine, you can try using that as well.
